Effect of food and gastric pH on the bioavailability of grepafloxacin.
Trial report in Clinical pharmacokinetics, 1997. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Two open crossover studies were conducted to investigate the effects of food or concomitant treatment with the histamine H2-receptor antagonist famotidine on the pharmacokinetics of the new fluoroquinolone grepafloxacin. Each study involved 16 healthy male volunteers. In the first study, participants received grepafloxacin 600 mg, either after fasting or after consumption of a standard high-fat meal. There were no significant differences in any pharmacokinetic parameter under the fasting or nonfasting conditions. In the second study, participants received grepafloxacin 400 mg, either alone or after infusion of famotidine 20 mg; additional doses of famotidine were given, if necessary, to maintain intragastric pH above 6. Famotidine treatment had no significant effect on grepafloxacin pharmacokinetics. The results of these studies indicate that neither food nor the elevation of gastric pH influence the absorption or bioavailability of grepafloxacin. Therefore, grepafloxacin can be administered with or without food.
